Thanks a lot, Zeke!
<font face="Verdana, Arial, Helvetica" size="2">As thrust drops off with speed its not a very useful operational parameter. i.e imagine trying to set a thrust figure while the aircraft is moving on a takeoff roll, its decreasing as the speed builds up, much easier to set a torque and temperature to get the power required.</font>
This statement is just what I have been looking for! What a simple and clear explanation
. Of course you can explain both jets and turbo props in terms of both power and thrust (depending on what we're discussing), but this clearly explains
why power is most commonly used for TP and thrust (force) is used for jets.
God I like this forum!
